Abstract
Mixed signal circuit (4, 4′) for an electronic, protected control or regulation system, including a connecting bus for the connection of an external module (9, 9′) and one or more external and/or internal sensor inputs (2, 2′) for the connection of sensor modules, in which case the inputs can receive sensor data as well as test data (14, 15) which safeguard the sensor data, and in which case the test data being used on the input side for safeguarding the sensor data are also used internally for safeguarding the sensor data which are reprocessed internally.
The invention furthermore relates to a data transmission method with several data transmission steps (18, 18′, 16, 16′, 6, 6′, 7, 7′, 8, 8′) as well as to the use of the above mixed signal circuit in an electronic, protected motor vehicle control or regulation system.
